Preposed small seed sower

Abstract

The invention discloses a preposed small seed sower. The preposed small seed sower comprises a main machine frame, an auxiliary machine frame, a ground wheel, a suppressing wheel, a cross beam, an oilcylinder, a seed box, a furrow opener and a soil covering plate, wherein the ground wheel is mounted at the front end of the main machine frame; the suppressing wheel is mounted at the back end of the mainmachine frame; the seed box and the furrow opener are mounted above and below the main machine frame respectively; the soil covering plate is mounted at the back end of the furrow opener; and the auxiliary machine frame is mounted at the front end of the tractor. A sowing mechanism is mounted in a preposed manner, so that the sowing quality is guaranteed; and after sowing, under the rollingaction of the tractor, the preposed small seed sower also plays a compacting role.

Description

technical field [0001] The invention relates to a front-mounted small-grain seeder, in particular to the research field of agricultural machinery suitable for sowing small-grain after land rotary tillage leveling. Background technique [0002] Existing mechanized small-grain seeders are generally pulled by the rear of the tractor. Small-grain sowing (such as rapeseed, millet, etc.) has strict requirements on the sowing depth. If the sowing is too deep, it will not be easy for seedlings to emerge, and if the sowing is too shallow, it will not be easy for seedlings to emerge due to insufficient water. Although there is currently the technology of front and rear wheels profiling the ground to ensure uniform sowing depth, the sowing equipment is rear-mounted, and the wheel tracks rolled by the tractor's four wheels cause local unevenness and soil compactness to appear again on the leveled land. Re-sowing seriously affects the sowing effect of small seeds. The human hand-push sm...

Problems solved by technology

[0002] Existing mechanized small-grain seeders are generally pulled by the rear of the tractor. Small-grain sowing (such as rape, millet, etc.) has strict requirements on the sowing depth. If the sowing is too deep, it will not be easy for seedlings to emerge, and if the sowing is too shallow, it will not be easy for seedlings to emerge due to insufficient water.

Although there is currently the technology of front and rear wheels profiling the ground to ensure uniform sowing depth, the sowing equipment is rear-mounted, and the wheel tracks rolled by the tractor's four wheels cause local unevenness and soil compactness to appear again on the leveled land. Re-sowing seriously affects the sowing effect of small seeds

The human hand-push small seed planter can overcome the above defects, but it is labor-intensive and inefficient, so it can only be used for small plots such as greenhouse vegetables.
